Radiohead recorded In Rainbows over two years with producer Nigel Godrich, incorporating various musical styles. The album artwork was designed by longtime collaborator Stanley Donwood, who experimented with photographic techniques to create colorful, organic images reflecting the album's sensual sound. Radiohead released In Rainbows first as a digital download in 2007, then physically on CD and vinyl with expanded artwork and tracks. It was their first album widely available on digital music stores.
